I reset a new Trip B to track efficiency over a long period now that temps are in the 40's and 50's, to compare to my average up to this point (delivery in early June in TX, so averaged probably mid to high 80's).
So far, I'm not seeing an appreciable difference, most notably due to not having to use any HVAC at all. For one I'm typically already dressed for the ambient temp anyway, and I also warm the cabin before leaving and it then stays fairly well insulated (especially if it's sunny). For example, today it was in the low 40's yet my cabin never got below 65, after pre-heating to about 68-69, through a couple hours of driving around town, including a few entry and exits of the vehicle.
Overall, I don't expect to have to use cabin heating unless it gets into the 30's or below, and that's a significant part of the impact of cold weather besides the battery physics.
Recurrent is showing that owners should expect a 16% range reduction at around 21 degrees vs. the baseline range at an optimal temp of 90 degrees. I don't know exactly how many are in their fleet or how much data is in that though (haven't had a full winter of data clearly). That is about the same as what they say about an eTron (15% loss at 21 deg vs. optimal at 86 deg), for what it's worth, and I found their data to be pretty accurate with that.
